CAR-COUPLING.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed December 27. 1915. Serial No. 68,668.

To all whom it may ('O'ILCOTH.

lie it known that l. An'rm n J. Emma-1r, a citizen of the United States: residing at Cleveland, (luyahoga county, ()hio, have invented new and useful Improvements in ('ar-(ouplings of which the following is a specilicatioh, reference being had to the accompanying drawings, in which Figure 1 is a section of a car coupler em bodying my invention Fig. 1 is a plan thereof; Fig. 3 is an elevation of the lock lifter; .l ig. -t is a plan of the lifter, and l figrs. 5 and 6 are sections on lines VV and V IV I respectively of Fight-3.

l\l" invention relates to car couplers and particularly to the lock lifting mechanism herefor.

I have found in certain types of couplers now in use, that through carelessness of workmen the lifter is sometimes applied in reversed position with the result that while the lock may be lifted, the coupler is usually rendered inoperative.

The object of the present invention is to prevent such occurrences and to this end I have designed the lifter and coupler head so that the lifter can be applied to the .coupler head and the look only in the proper the lock C and by which engagement the,

lock is supported amd operated. Onits rear side the lifter has-also angled faces 4 and 5 which coiiperatewith corresponding faces on the projection 6 at the rear of the coupler cavity and serve not only to prevent the trunnions from disengaging from the recesses in the look but also act as an anticreep or down hold for the lock.- To insure the proper cooperation between the lifter and the lock and the lifter and the anticreep projection (i. the lifter E near its upper end is made of wedge shape in cross secwhich in the upper portion is wider than the web i at its forward side. It will therefore be seen that thelit'ter cannot be inserted into the coupler head in reversed position since its rear side is too wide to pass through the small forward extremity of the lifteropenmg The terms and'expressions which I have employed are used as terms of description and not of limitation, and I have no inten-' tion, in the use of such terms and expressions. of excluding any mechanical equivalent for the features shown and described, but recognize that various modifications are possible within the scope of the invention claimed.

\Vhat I claim is:

1. In a car coupler, a lock and a lock-lifter, the lifter being capable of engagement'with the lock in two positions only one of which is an operative position, and a coupler-head having a wedge shaped lifter opening, the shank of the lifter being also wedge shaped to conform to the lifter opening and permitting the application of the lifter to the lock in operative position only.

2. In a car coupler. a coupler head, a lock, and a lock-lifter, said lifter having trunnions atits lower end and faces at the rear side of said lower end adapted to coiiperate with the coupler head when the lifter is in normal relation with the lock and the lock is in lowermost position to act as a down hold for the lock. a slot in the lock adapted to I receive said lifter trunnions,sai' lfterbeing' capable of engagement with said lock in two diametrically opposite positions, only one of which is an operative position, the coupler head hav'in; an aperture of non-symmetrical cross section corresponding to the cross'sectional shape of the lifter at its uppe and being thereby adapted to ,'per n,iififjte engagement of the lifter and thelock in operative position only.
